Lanthanide(Ⅲ) Fluoresence “Tetragroup Effect” Complexes of 4-(3,5-Diphenyl-2-Pyrazolin-1-) Benzenesulfonic Acid

本文首次报道了十四种以荧光“四分组效应”反映热力学稳定性“四分组效应”的镧系 4- ( 3,5-二苯基 -2 -吡唑啉 - 1 - )苯磺酸配合物 ,〔Ln( Dpbs) 2 · ( H2 O) 4 〕Dpbs· n H2 O,其中 Dpbs=4- ( 3,5-二苯基 - 2 -吡唑啉 - 1 - )苯磺酸根离子 ,n=0或 2的合成及以元素分析、电导、溶解性、X-射线粉末衍射、热天平、红外、紫外和可见光及荧光光谱等数据对配合物结构表征和性质的研究。

Fourteen new lanthanide(Ⅲ) fluoresence “tetragroup effect”complexes of 〔Ln(Dpbs) 2·(H 2O) 4〕Dpbs·n H 2O,where Dpbs=4 (3,5 diphenyl 2 pyrazolin 1 ) benzenesulfonate ion,n=0 or 2,have been prepared and characterized by elemental analysis,conductivity measurements,solubility,X ray powder diffraction,thermal analysis,IR,UV Vis and fluoresence spectra.The thermodynatic property of the complexes reflected by fluoresence “tetragroup effect”are firstly observed.
